Detection of a Thermal Spectral Component in the Prompt Emission of GRB 100724B
Sylvain Guiriec, Valerie Connaughton, Michael S. Briggs +29
Observations of GRB 100724B with the Fermi Gamma-Ray Burst Monitor (GBM) find that the spectrum is dominated by the typical Band functional form, which is usually taken to represen…
Photometric redshifts for GRB afterglows from GROND and Swift/UVOT
T. Krühler, P. Schady, J. Greiner +18
We present a framework to obtain photometric redshifts (photo-zs) for gamma-ray burst afterglows. Using multi-band photometry from GROND and Swift/UVOT, photo-zs are derived for fi…
GRB 050502B optical afterglow: a jet break at high redshift
P. Afonso, J. Greiner, E. Pian +9
Aims: GRB 050502B is well known for the very bright flare displayed in its X-ray light curve. Despite extensive studies, however, the optical light curve has never been discussed a…
Time-Resolved Spectroscopy of the 3 Brightest and Hardest Short Gamma-Ray Bursts Observed with the FGST Gamma-Ray Burst Monitor
Sylvain Guiriec, Michael S. Briggs, Valerie Connaugthon +25
From July 2008 to October 2009, the Gamma-ray Burst Monitor (GBM) on board the Fermi Gamma-ray Space Telescope (FGST) has detected 320 Gamma-Ray Bursts (GRBs). About 20% of these e…
Fermi detection of delayed GeV emission from the short GRB 081024B
Fermi LAT Collaboration, Fermi GBM Collaboration
We report on the detailed analysis of the high-energy extended emission from the short Gamma-Ray Burst (GRB) 081024B, detected by the Fermi Gamma-ray Space Telescope. Historically,…
